Iterate over fields in typesafe config file

In my Scala application I have a configuration like this: 

datasets {
    dataset1 = "path1"
    dataset2 = "path2"
    dataset3 = "path3"
}

Ho do I iterate over all the datasets to get a map [dataset, path]?

You can try my scala wrapper https://github.com/andr83/scalaconfig - it supports reading native scala types directly from config object:

val datasets = config.as[Map[String, String]]("datasets")

You can call entrySet() after getting config with getConfig()

import scala.collection.JavaConversions._
val config = ConfigFactory.load()
val datasets = config.getConfig("datasets")
val configMap = datasets.entrySet().toList.map(
  entry => (entry.getKey, entry.getValue)
).toMap

You will end up with a Map[String, ConfigValue].
